POWER TIMER K SOURCE ELECTRIC SONIC IMPLODER The invention relates to sound making devices and, in particular, to such devices that are adapted to be submerged in a liquid medium and employ electric current traveling through the medium causing expansions and contractions therein thus creating sound pulses.

As seen, for example, in U.S. Pat. No. 3,230,506 there are known underwater devices for providing sound and even, as disclosed in US. Pat. No. 3,007,133 such devices which depend, as in this case on the formation of a gas bubble by heating the water using spark plugs. In the present case a plurality of continuous conductors are extended through the medium being connected between a pair of baffles which partially define the limits of the generated steam bubble. As the bubble expands between the baffles it extends into cooler water strata causing it to burst. The resulting inrush of water generates the desired sound impulse. The device may be used to repel fish from water inlets where they may otherwise be killed as in connection with nuclear power stations.

One object of the invention is to provide a new and improved underwater sound making device.

Another object of the invention is to produce an underwater sound device of simple construction and easy maintenance.

Other objects and advantages of the invention may be appreciated on reading the following description of one embodiment thereof which is taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a view showing the principal components of the underwater imploder; and

FIG. 2 is a section taken on the line 2-2 of FIG. 1 showing the triangular configuration of the underwater conductors in the imploder.

Referring to the drawings, a low voltage source 2 capable of generating 2 to 40 volts is connected to a timer 4 capable of cutting off current to bare wire conductors 6.

The conductors 6 extend between a pair of baffle plates 8, the conductors and plates being submerged in water medium 10. The conductors are arranged in a triangular configuration being capable of becoming cherry red hot on passage of relatively high amperage current and producing steam bubbles in the water the hottest point of which is located near the mid point between the three conductors. As the bubble expands outwardly from this point it makes contact with the baffles further expanding between them until the relatively cooler water above and below the baffles causes the steam bubble to burst due to change of phase thus producing the resulting implosion.

The resistance of the three conductors is sufficiently low that by far the greatest proportion of the current is through the conductors as opposed to the liquid medium in which they are submerged. The high current generates a steam temperature over 600F and, in fact. produces super heated steam. The timer is optional but is thought to produce sharper pulses than would be generated otherwise.

The conductors may be fabricated of a metal alloy which resist melting at and somewhat beyond the operating conditions particularly temperature values established for the system. At these temperatures the wire conductors will be self cleaning. It is to be noted that the system employs no moving parts which is conducive to durability and ease of maintenance.

Various modifications of the invention may be effected by persons skilled in the art without departing from the scope and principle thereof as defined in the appended claims:

What is claimed is:

1. An underwater sound imploder comprising at least one bare wire conductor submerged in a liquid medium, a low voltage source connected to said conductor for supplying a current therein for generating heat below the vaporization temperature of said wire, and a pair of opposing baffle plates submerged in said medium and disposed respectively at the ends of said conductor whereby the implosion generated by said device is confined substantially to the region between said bafis connected to said source and said conductors.
